About Framework not found BigInt problem

[xuanwenchao]

I have created a new test project and podfile content is:
platform :ios, '16.4'

use_frameworks!

target 'VaneTrust' do
pod 'SubstrateSdk', :git => 'https://github.com/nova-wallet/substrate-sdk-ios.git', :tag => '1.1.0'
end

post_install do |installer|
installer.pods_project.build_configurations.each do |config|
config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
end
end

this is result after run pod install:
Analyzing dependencies
Pre-downloading: SubstrateSdk from https://github.com/nova-wallet/substrate-sdk-ios.git, tag 1.1.0
Downloading dependencies
Installing SubstrateSdk 1.1.0
Generating Pods project
Integrating client project

It looks good.
but I Met a problem when running the build in Xcode.

ld: framework not found BigInt
clang: error: linker command failed with exit code 1 (use -v to see invocation)
